Doritaenopsis plant named ‘Moon N12’

ABSTRACT

A new and distinct cultivar of  Doritaenopsis  plant named ‘Moon N12’ has white petals and sepals with light purple shadow near the labellum, upright and sturdy flowering stems, and excellent postproduction longevity.

Botanical classification: Doritaenopsis sp.

Variety denomination: ‘Moon N12’.

The present invention relates to botanical classification/ cultivardesignation: Doritaenopsis Orchid cultivar Moon N12.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar ofDoritaenopsis Orchid, and hereinafter is referred to by the cultivarname, ‘Moon N12’.

The new cultivar is a planned breeding program conducted by the inventorin Tainan, Taiwan. The objective of the breeding program is to createnew uniform pot-type Doritaenopsis Orchid cultivars having attractiveflower coloration.

The new cultivar was discovered by the inventor from within the progenyof a cross-pollination of two unnamed proprietary selections ofDoritaenopsis and Phalaenopsis Orchids, not patented, on Oct. 18, 1999,in a controlled environment in Tainan, Taiwan.

Asexual propagation by tissue culture in a laboratory in Tainan, Taiwanhas been used to increase the number of plants for evaluation and hasdemonstrated that the unique combination of characteristics as hereindisclosed for the new Doritaenopsis Orchid, ‘Moon N12,’ are retainedthrough successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe basic characteristics of a new cultivar which, in combination,distinguish this Doritaenopsis Orchid as a new and distinct cultivar:

-   -   1. Flowers whose width in front view is broad, about 11 to 13        cm.    -   2. Flowers having a persistent habit.    -   3. Upright, freely branching and sturdy flowering stems.    -   4. Excellent postproduction longevity.

Plants of the new cultivar differ primarily from plants of the parentcultivar in flower color.

Plants of the new Doritaenopsis Orchid can be compared to plants of themale parent Phalaenopsis and the female parent Doritaenopsis. Inside-by-side comparisons conducted in Tainan, Taiwan, plants of the newDoritaenopsis Orchid differed from plants of the male parentPhalaenopsis and the female parent Doritaenopsis in the followingcharacteristics:

-   -   1. Plants of the new Doritaenopsis Orchid are bigger than plants        of the male parent Phalaenopsis and the female parent        Doritaenopsis.    -   2. Plants of the new Doritaenopsis Orchid have broader leaves        than plants of the male parent Phalaenopsis and the female        parent Doritaenopsis.    -   3. Plants of the new Doritaenopsis Orchid have shorter        inflorescences than plants of the male parent Phalaenopsis and        the female parent Doritaenopsis.    -   Plants of the new Doritaenopsis Orchid have stronger peduncles        than plants of the male parent Phalaenopsis and the female        parent Doritaenopsis.
